UNITED sTATEs PATENT oEEIo ALEXANDER DARLING, OF DUBLIN, ONTARIO, CANADA, ASSIGNOR OF ONE-HALF TO EDWARD JOHN LITT, OF STRATFORD, CANADA.

SN OW-PLOW.

Specification of Letters Patent.

Patented June 2, 1908.

To all whom it may concern:

Be it known that I, ALEXANDER DARLING, residing at Dublin, in the county of Perth, in the Province of Ontario, Canada, have invented certain new and useful Im rovements in Snow-Flows, of which the fol owing is the specification.

My invention relates to improvements in snow plows, and the object of the invention is to devise a snow plow, which may be readily adjusted to throw the snow on either or both sides of the track as desired, and also insure of its bein delivered below the level of the top of the p ow, and thereby prevent any liability of the snow getting on to the top of the engine.

A further object is to provide a cupola in such a position that the man running the plow can readily see and control the o eration thereof according to the nature 0 the drifts with which it has to contend.

To effect these objects I have constructed my plow with a front sloping scoop, a converging share located at the rear upper end of the scoop and having the planes of the two faces of the share at right angles to the plane of the scoop, a divider plate hinged at the converging front end of the share, uprights located at each side of the front of the scoop and connected at the top by a cross bar and by rearwardly extending bars to the plow at apoint above the top of the converging share, cords or chains connected to the top of the divider plate and to a drum above the converging share, which is designed to be manipulated to adjust the divider plate, a cupo a immediately above the converging share pins extending through the scoo on each side of the divider plate near the ont edge, bell cranks extending under the scoop and connected at oneend to the ins, and levers connected by rods to the bel cranks, the

said levers extending into the cupola and the parts being otherwise constructed and arranged in detail as hereinafter more particularly explained.

Figure 1 is a (perspective view of a snow plow constructe in accordance with my invention. Fig. 2 is a longitudinal section.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the mainbody of the plow and B B the trucks, which carry it.

C is the front sloping scoop and D a converging share the planes of each side of which are at right angles to the plane of the scoop. The shares are formed wider at the top than at the bottom to form slightly outwardly inclined sides, thereby leaving the bank of snow inclined to prevent it sliding on the track.

E is a divider plate, which is suitably hinged at the apex of the converging share.

F are upright frames substantially tri-angular in form and carrying at the top a cross bar G.

G are bars, which extend rearwardly from the apex of the tri-angular sideframes F to a plate D immediately above the converging share D.

E is a re-inforcing cutting edge strip at the front of the divider plate E.

E is a double flange secured on the top of the divider plate E and designed, when the divider plate is thrown to one side, for directing the snow along the side of the divider plate and preventing it mounting over the top of the same.

E is a double'cutting flange extending to each side of the bottom edge of the divider plate. The plate E is made acutting plate in order, when the divider is moved laterally the cutting edge will clear the surface of the scoop from ice or snow.

I is acord connected to the top of the strip E and extending around the guiding pulleys I at the top of the tri-angular frames F and backwardly along the bars G around the drum J journaled in suitable bearings as indicated, and mani ulated by means of a hand wheel J provided with a Worm, which co-acts with the worm wheel J at thebottom of the shaft of the drum. The drumis supported on a suitable bridge K extending across the cupola L, which it is to be noted extends immediately behind the apex of the converging share and below the top of the same.

M are pins located one on each side of the front edge E of the divider plate E. The pins M extend through the slo ing scoop and are secured on one end of the fiell cranks M, which are journaled in brackets M at the bottom of the scoop and are connected by rods M to the manipulating levers M, which are fulcrumed in brackets M on the bottom or floor of the snow plow body. The levers M extend through slots L in the floor of the cupola and thereby provide a means within reach of the man controlling the plow for manipulating the pins M.

When it is desired to throw the divider plate E to either side, so that the snow that is forced up the scoop may be carried to the to cause the pin M to recede when the hand wheel J may be manipulated to adjust 'the divider plate, so that the front edge E will lie close to one of the uprights of the tri-angular frame F.

It will be noticed that the front edge of the divider plate is at an incline to the top and bottom, that is to say is not at right angles to either the top or bottom, nor parallel to the back edge. The reason is so that the divider plate when adjusted laterally will have its edge lie close to the uprights of the tri-angular frame F and present no opening above the bottom in which the snow would be likely to choke, and prevent the working of the plow on that side, which is not actually in use when the divider plate is adjusted to throw the snow to the opposite side.

It will be seen that I provide an angle plate D at the top of each side of the converging share and this is desi ned to prevent the snow from rising up a ove the top of the share.

By the use of a divider or divider plate, such as I describe, the'man controlling the plow can with facility throw the divider towards one side and then towards the other or leave it central according to the set of the track ahead of him, that is shape and position of the drifts on the track. In case of a double track also it is essential that the divider plate be thrown to one side, so as to throw the snow on the opposite side to that in which the adjacent track is located.

What I claim as my invention is:

1. In a snow plow, the combination with the car body and the front sloping scoop, of a converging plow-share located at the upper rear end of the sloping scoop and having the plane of the faces of the share substantially at right angles to the plane of the scoop, a divider or divider plate hinged at the front converging edge of the low-share and extending forwardly from tlie same, means for swinging the front of the divider from the center to either side, a cupola located immediately above the converging plowshare in which the mani ulating devices are located, pins extending t rough the. sloping scoop on each side of the bottom front edge of the divider and means for raising and lowering said pins as and for the purpose specified;

2. In a snow plow, the combination with the car body and the front sloping scoop, of a converging plowshare located at the upper rear end of the sloping scoop and having the plane of the faces of the share substantially at right angles to the plane of the scoop, a divider or divider plate hinged at the front converging edge of the plow-share and extending forwardly from the same, means for swinging the front of the divider from the center to either side, a cupola located immediately above the converging plowshare in which the manipulating devices are located,

.pins extending through the sloping scoop on each side of the bottom front edge of the divider, the bell cranks supporting the pins, levers suitably fulcrumed and extending up in the cupola and the rods connecting the levers to the bell cranks as and for the purpose specified.

3. In a snow plow, the combination with the car body and the front sloping scoop, and a converging plowshare located at the upper rear end of the sloping scoop, of a divider plate hinged at the front end of the share, and a bottom cutting flange extending on each side of the bottom edge of the divider plate and lying on the surface of the scoop as and for the purpose specified.

4. In a snow plow, the combination withthe car body and the front sloping scoop, and a converging plow-share located at the upper rear end of the sloping scoop, of a divider plate hinged at the front end of the share and a double to flange extending over each side of the divid er plate as and for the purpose specified.

5. In a snow plow, the combination with the car body and the front sloping scoop, and a converging plow-share located at the upper rear end of the sloping scoop, of a divider plate hinged at the front end of the share, a double top flange extending over each side of the divider plate and an angle plate extending outwardly from the top edge of each side of the converging share as and for the purpose specified.
